mesa: fix error handling for glMaterial*
Trigger GL_INVALID_ENUM error if the face paramter is not a valid value.
Trigger GL_INVALID_VALUE error if the GL_SHININESS value is out side
[0, ctx->Constant.MaxShiniess].
v2: fix the max shininess value.
v3: suggested by Brian, move the face check into glMaterialfv function
to reduce code duplicate. Also, refactor the error message.
